yes,
the commun "bible" ("graphic charter"? it's the litteral translation  
of the french formulation) is:
- how to use the logo on background colors (show if it is in a white  
box or a transparency background), on white background color, on black  
background color
- how to use the logo for RGB purposes (eg: web), for CMYK (print),  
for just a few colors (Pantones colors, Tee-Shirt, ? )
the "bible" is just a .pdf file with some samples and a "how to"

About Logo use:
your logo is not registered (?, ?, ?, etc) ?and in fact, you don't  
mind (FFmpeg is well know ;-))

on the web site, just add a "press/logo" link with a license and a  
checkbox (to access to the download  "tarball" file, .zip or .gz)
the same license will be above the checkbox, and in the .pdf (and in  
plain text if you want)

you can write something like this (I don't use english formulation,  
but you certainly encountered it)

"License Agreement:

FFmpeg and its logo is the property of the FFmpeg project.

We grant to you a non-exclusive, non-transferable worldwide license to  
use the Logo for the Permitted Uses (as defined below). Unless the  
activity or use is a Permitted Use, you cannot do it. All other rights  
in and to the Content, including, without limitation, all copyright  
and other intellectual property rights relating to the Content, are  
retained by the FFmpeg project (a real name will be better) or the  
supplier of the Content (the real name here, Mans?), as the case may be.

You can only use it according to the graphic charter,

and add the limitations etc (pornographic use, re-sale, alterations,  
forbidden to use by a non-GPL/LGPL compliant app , etc)"

just some notices about the logo:

because of the rescale, the FFmpeg text has some different bold (some  
letters are bigger than others)
it will be better to clean it
eg:

no real need)

for "non-2 colors" (eg: web or print), it will be better to add some  
"less-basic green" (see eg#2)

----------------------------

?and my advise as graphist:
the dct zigzag is only know by developpers
add a "more compact look", and your logo will be better identifed by  
others (they will not identify the dct -'cause they don't know it- but  
they will easier recognized the "shape")
